Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed July 21, 190s. serial No. 444,656.

To all whom 'it may concern:

citizen of the United States, residing at Boise, in the county of Adaand State of Idaho, have invented certain new and useful Improvements inOil-Separators, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to improvements in devices for separating oilfrom the exhaust steam of steam engines and for analogous uses.

The object ofthe invention is to provide a simple, inexpensive andpractical device of the character in which the oil will be separatedfrom the steam by reason of the expansion of the latter.

With the above and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which 'gure 1 is a vertical section throughthe improved oil separator showing its connection with the exhaust froman engine; and Fig.l 2 is a horizontal section taken on the planeindicated by the line 2 2 in Fig. 1.

In the drawings 1 denotes a portion cf an engine 2 the steam exhaustpipe leadingr from t e same and3 the body of the improved oil separator.This body is in the form of a verticall disposed metal cylinder having aflanged ower end or'head 4 riveted to its bottom, as shown at 5, and anu er head or top 6 rovided` with an interna y threaded depen ing ange.which is screwed upon rltile e steam exhaust pipe 2 projects through thetop 6 of the body, whichlatter providesa chamber in which the steam mayexhaust so that the oil and the water composing the steam will separateand collect upon the bottom of the body or chamber and since the oil islighter than water it will float upon the .same and may be drawn offthrough a faucet 8 arranged in one side of the body at a suitabledistance from its bottom. The water is drawn off from the body throughan outlet pi e 9, the inner end of which is controlled by a Eoat valve10. The latter is in the form of a plug valve arranged upon the lowerend of f an upright stem 11 carrying a iioat 12. Said Be 1t known thatI, AMos E. EMBREE, a l

valve 10 is guided in its movementtoward and from its seat by a cage 13in which it is arranged. Upon the outside ofthe body 3 is rovided a gageglass 14 to indicate the evel of the water and in said body, adjacent toits bottom may be provided a hand hole 15 which will permit the interiorof tie body to bel readily cleaned. The hole 15 is covered by a suitableclosure 16.

17 denotes an outlet or exhaust pi e leading from the top 6 of the bodyandp 18 denotes a plurality of supporting le carried b the bottom 4 forsupporting t e device a ove the floor or other support.

Having thus described the invention what is claimed is:

' 1. An oil separator comprising an expanding and se arating chamberhaving an outlet and an in et to receive the exhaust steam, means fordrawing off the oil from said chamber, a water outlet ipe extending intothe lower portion of the c amber and having an upturned end formed witha cone-shaped valve seat and an externally screw threaded portion, acone-shaped valve, a stem projecting upwardly from the to of the valve,a float u on the u )per end o said stem, and a guide iibr the va ve stemand comprising an internally screw threaded sleeve engaged with thethreaded portion of theupturned end of the water outlet pipe and 4formedat its top with upwardly and inwardly projecting guide lingers toslidably receive' the valve stem between their spaced upper ends,substantially as described.

2. The herein described oil separator comprising a cylinder expandingand vcollecting' chamber, a downwardl propctin Aiexhaust steam inletpipe exten ing t roug the top of the same, an upwardly projectin outletpipe projecting from the top of said c amber, supporting legs at thebottom of sald chamber, a sig t gage for indicatlng the @level of li uidin the chamber, a faucet for drawing o the oil from said chamber, awater outlet pipe extending into the bottom portion of the chamber andhaving an upturnled end formed with a cone-shaped valve seat and with anexternally screw threaded portion, a cone-shaped valve, a stem projectir from the top of the valve, a float upon the* top of said stem, and aguide iur the valve stem and consisting of 'a sleeve screwed upon thethreaded ortion of said upturned end of the {vater out et ipe and formedat its top with 5 upwardly an inwardly projecting fingers to shdablvreceive the valve stem between them.

In testimony whereof I hereunto aix my signature in the presence of twowitnesses,
